He shares his Japanese name—which can be taken to mean "wisdom" or "reason" (智)—with the creator of the Pokémon franchise, Satoshi Tajiri. His English surname is a pun of the original English motto, "Gotta catch 'em all!."

In the anime

Character

Ash's main goal in life, as described in the first episode, is to be the world's greatest Pokémon Master. Ash began his journey at the age of 10 as a warm-hearted and well-intentioned but stubborn, rash and amateur Pokémon Trainer. He was forced to accept the cheeky Pikachu from Professor Oak as his starter Pokémon because he carelessly broke his alarm clock in his sleep and woke up late on the day he was set to get his first Pokémon. He was determined to achieve his goal, however, and when Pikachu saw that he was willing to compromise his own safety to keep it safe he formed a strong bond of friendship with Pikachu. This would set his course for the future.

However, from that point, Ash still had a lot to learn about becoming a Trainer. The first Pokémon he caught, was caught by luck, as he knew absolutely nothing about battling, and was hesitant to admit it whenever he was wrong. Many of his first GymBadges were given to him merely out of gratitude for his assistance rather than claiming an actual victory in battle over the Gym Leaders; of his first five Gym battles, only his victory over Lt. Surge was an actual victory. Every time he thought he was doing well, he would somehow cross paths with his childhood rival, Gary Oak. He always reminded Ash that he was always a step or seven behind, with Gary catching around forty-five Pokémon by the time Ash had only caught his seventh. This hampered matters further when, owing to his inexperience, his Charizard, one of his most powerful Pokémon, refused to listen to him until Ash could prove himself to the powerful Fire type.

Over time, Ash's dedication to his goal paid off. After earning his first eight Badges he went on to compete in the Indigo League, advancing to the fifth round - one further than Gary, and ending up in the top 16. After recovering from his defeat, he continued on to improve his skills; take on new challenges; and compete in more Pokémon League competitions - triumphing in the Orange League and the Battle Frontier.

Ash has changed a great deal over the course of the series, particularly in regards to his skill at Pokémon training, but his earnestness, rashness, and determination have remained. Never straying from his goal, he has remained loyal to his friends, his family, and his supporters, but most of all his Pokémon. Ash became a great Trainer by learning to find and use the inner strength of each of his Pokémon by bonding with them. For example, when he received a banner filled with prints from his Pokémon in The Unbeatable Lightness of Seeing!, he knew which Pokémon placed specific prints, showing his close bond with them. He also learns where their hidden abilities lie, as well as resorting to unorthodox strategies when fighting particularly challenging opponents. For example, he uses his Pikachu's speed to outmaneuver larger foes and attack. In another instance, his Charizard defeated Gary's Blastoise by causing the field to overheat before mounting a close-quarters attack while Blastoise was blinded by the steam. He also prefers to train a Pokémon to be the best it can without forcing it to evolve, as evidenced by his treatment of Gligar in Fighting Fear With Fear!. He is happy when his Pokémon evolve but lets them choose whether or not they want to evolve instead of forcing them.

Early on, Ash originally trained not to further himself but instead to catch more Pokémon than Gary. He later slowed his pace which allowed him to focus on the individual traits of each Pokémon. At the Johto League Silver Conference, with great humility and maturity, Ash finally won a battle against his old rival, signifying a great milestone in his history. His maturity has also increased in his dealings with Pokémon. This is shown when a Mankey stole his hat in Primeape Goes Bananas, he screamed and yelled at it, even climbing trees just to get his hat back, but when an Aipom did the same in Slaking Kong, he stated merely that he would feel strange without a hat. When Aipom stole his hat again in Setting the World on its Buneary!, however, while it was under his ownership, he chased after it in the same manner as before.

In most episodes of the anime, especially those during the Johto League saga, Ash befriends someone who will influence him and cause him to strive to become a better Trainer. Although he is not a dependent individual, he is still young and has learned to make his way relying on his friends, particularly the maternal skills of Brock. The honor of "best friend" is usually reserved for Pikachu but Ash has come to see his closest human friends in the same light over time; using the term for Misty and Brock in Gotta Catch Ya Later! as well as May and Max in Battling the Enemy Within.

Although viewed as a normal human, Ash does have some special abilities, as he is said to have the same aura as Sir Aaron, a legendary hero, and is theoretically able to manipulate it in much the same way. Therefore, he made a connection with Sir Aaron's Lucario. However, he has not received any training in this field, opting to continue his Pokémon journey instead. He has also been likened to an ancient aura guardian in The Keystone Pops!, who also had a partner Pikachu. Later, in Pokémon Ranger and the Kidnapped Riolu! Parts 1 and 2, Ash uses aura again to locate a lost Riolu and read Riolu's mind as well. This time, however, he merely senses the aura, rather than manipulating it.

Ash has also participated in Contests. He has a Contest Pass for the Sinnoh region, as well as one for the Hoenn region as it was required to watch one of the Contests held there. Ash carries half of a broken Poké Ball with him everywhere, while Gary has the other half, as a symbol of their ongoing, but now friendly, rivalry; Misty's special lure, which she sent to him as a gift; and half of a Ribbon he received in a Contest against May before she left the group to compete in Johto. Ash also participated in the Wallace Cup on the suggestion of Wallace but he lost in the third round.

Ash soon obtained all of the Sinnoh Gym Badges. During his battles in the Lily of the Valley Conference, he managed to advance to the Top 4, during which time he defeated his long-time Sinnoh rival Paul for the first time, and fought against Tobias, becoming the only known Trainer to defeat his Darkrai. Though he lost later on in the battle, he seems to be okay with losing, as he has become closer to his Pokémon than ever before. Ash, Dawn, and Brock then set off on their own paths to follow their respective dreams, with Brock saying he will no longer be joining Ash on his next journey.

In the Best Wishes series, Ash came with Professor Oak and his mom on a trip to the Unova region. After losing in a battle to Trip and seeing the power of the legendary Zekrom, Ash became interested in traveling Unova to meet new Pokémon, as well as new friends. He is now currently in journey in Unova, first bringing along only his Pikachu as he did in Hoenn.

Family

A young Ash

Ash is an only child that lived with his mother, Delia Ketchum, until he left for his Pokémon journey at the age of ten.

His father has not been introduced. The anime suggests that his father was once a Pokémon Trainer who began his journey in Pallet Town, and that he is still living. In the original, he is also confirmed to have a grandfather, and his son (Ash's father) followed his footsteps. An interview with the series' storyboarder confirmed Ash's father is a Trainer on his own journey. According to the same storyboarder, Ash's father may or may not be introduced in the series, depending on its necessity to further Ash's maturity and development as a Trainer.

Pokémon

A majority of Ash's Pokémon at Professor Oak's lab

As a Trainer, Ash has captured and befriended a sizable number of Pokémon over the course of the anime. His philosophy on training is that Pokémon are individuals and that a combination of trust, friendship and hard work are needed to overcome adversity. He seems to battle best with Pokémon that are similar to Pikachu: ones that are speedy and maneuverable, yet able to perform high-powered attacks; however, he is willing to work with any Pokémon that comes into his care. Ash's battle style is generally spontaneous and fairly unorthodox, and his Pokémon often reflect these traits.

Currently in rotation

In the Unova region, Ash does not keep the same party at all times like he had done previously. Instead, he swaps his on hand Pokémon (with the exception of Pikachu) with ones that are being stored at Professor Juniper's lab, much like he did with his Kingler and Muk in Kanto with Professor Oak.

Unofficial

Temporary

This section is for the Pokémon that Ash temporarily used. Many of which were rented and belong to another Trainer.

Ponyta → Rapidash

Ash borrowed Rapidash from Lara Laramie when it was a Ponyta after she was injured and could not ride it in the race. It evolved into Rapidash when it was racing against Dario's Dodrio. Thanks to the speed gained through the evolution, Ash and Rapidash were able to win the race.

The Pokémon League entrance exam instructor gave Ash a Weezing by having him choose his own set of Poké Balls provided by the instructor. It was used during the Pokémon League exam by battling the Instructor's Flareon and won.

Meowth was the final Pokémon used by Ash during the Pokémon League exam. It was up against the Instructor's Vaporeon in which Vaporeon froze the Meowth causing Team Rocket's Meowth to interfere with the battle by kicking the frozen one free. It was accidentally blasted off along with Team Rocket. The temporary switch was fixed in the next episode.

Ash commanded this Lombre during the battle with Team Rocket since Brock stayed behind in a stadium to perform with Corphish while Ash and the others went after Team Rocket after they took Lombre instead of Mawile.

Ash encountered Brock's Sudowoodo when the group was separated by Graveler and Golem. After stopping a fight, Ash went with Sudowoodo to get out of the maze and find Dawn and Brock. When they were found, Ash had Sudowoodo Mimic Pachirisu's Discharge to break a hole in the maze wall after finding them from the other side.

In the Ash and Pikachu manga

In The Electric Tale of Pikachu manga

Ash Ketchum is a starring character in The Electric Tale of Pikachu, a manga series based on the anime. Ash's journey in The Electric Tale of Pikachu follows roughly the same plot as in the anime: first traveling the Kanto region to participate in the Pokémon League, before embarking on a journey around the Orange Archipelago.

In the Magical Pokémon Journey manga

Ash and Brock in Magical Pokémon Journey

Ash, along with Misty and Brock, made cameo appearances in bonus chapters of the Magical Pokémon Journey manga. In the bonus chapters, Ash and his friends have mistakenly wandered into the world Magical Pokémon Journey is set in. The bonus chapters chronicle their attempts to return to their own world (of the anime) and their encounters with various aspects of the Magical Pokémon Journey canon which differ from the anime's canon (such as the use of Poké Balls).

In the movie adaptations

Ash with his friends in the movie 10 manga adaptation

Since Ash and his Pikachu have appeared in every Pokémon movie to date, likewise, Ash is a main character in every Pokémon movie manga adaptations. The same applies with Ash's team as they made similar appearances.

In the TCG

Ash's PokémonCards listed with a blue background are only legal to use in the current Expanded format.Cards listed with a silver background are legal to use in both the current Standard and Expanded formats.

The date of Ash's birth, according to Takeshi Shudo's anime novelizations, is 10 years, 10 months, and 10 days exactly prior to the day he began his Pokémon journey. Being that the same novelization declares that Pokémon Trainers obtain their first Pokémon in April of the year following their 10th birthday, and the anime itself began broadcast on the first of that month in 1997 in Japan, Ash's birthday, if April 1 was the first day of his journey, would be May 22.

When Veronica Taylor was interviewed in the documentary "Adventures in Voice Acting", she stated that during her audition for the role of Ash, he was known as Casey at the time. This name would later be given to a recurring character from Johto.
